We formulated 3M™ Hot Melt Adhesive 3750 to grab and seal quickly and meet the demands of high-volume production settings such as packing, woodworking and assembly. When heated to its specified melt point, this adhesive achieves a low viscosity/ high-flow rate and an aggressive hot tack that bonds to handling strength in seconds to help maintain high-tempo productivity.
Together these two properties increase the speed of carton closures and provide adhesion to wood, paperboard, corrugated and other fibrous substrates. It provides strong shear strength and low peel strength, which means your packages stay sealed and components stay bonded under most conditions.
Low-melt adhesives are beneficial in that they can be used to bond heat sensitive materials such as foam and a range of plastics. They provide a nearly instant bond, but when the bond is reheated, some varieties will soften, allowing the bonded surfaces to be separated. The aggressive hot tack nature of low-melt adhesives speeds up production and assembly operations that involve light gauge metals, some plastics and other non-fibrous materials in addition to building display boards, floral displays and hobby projects.
